Abstract摘要
物质是一种可再生资源:其自然作用等,可以重复利用自然资源,人类如植物、动物、森林、草原等,一些以可再生资源为原料的物质也可以认定为可再生资源(heet.,al,2016)。材料是在使用较少材料的过程中使用的:消耗的材料越少,可用的资源越多,使用的材料越多。材料在自己生产制造产品的过程中能耗较低,能耗主要是指目前工厂的用电量,因为目前的用电量主要是火电,而火电消耗大量的煤炭,因此降低了材料的能耗。里亚尔,相应耗煤量少,同时减少排放,具有低碳经济的复合特点。材料在自己的生产和制造过程中产品处于低污染状态,具体污染包括:水污染、空气污染、噪声污染、放射性污染、重金属污染等。产品寿命越长,使用寿命越长,在一定时间内消耗的量就越少。Material is a renewable resource: the natural role, etc., can be repeated use of natural resources, human, such as plants, animals, forest, grassland, some materials with renewable resources as raw materials can also be identified as a renewable(Heet.,al, 2016). Materials are used in the process of using fewer materials: the less material is consumed, the more resources are available, and the more materials are utilized. Materials in their own production and manufacturing products in the process of low energy consumption, energy consumption mainly refers to the consumption of electricity in the factory at present, because the current electricity mainly thermal power, and thermal power consumes a large amount of coal, so the lower the energy consumption of the material, corresponding consumed less coal, reduce emissions at the same time, the composite characteristics of low-carbon economy. Materials in their own production and manufacturing products in the process of low pollution, pollution specific include: water pollution, air pollution, noise pollution, radioactive pollution, heavy metal pollution, etc. The longer life of the product, the longer it will be used, the less it will be consumed in a certain period of time.

1.0 Introduction介绍

常用材料,天然高分子材料是唯一的可再生资源,而木材材料是唯一的碳汇容量,而木质材料则符合低碳材料的特点,特别是木材,木材具有所有低碳材料的特点,木材工业具有低能耗的优势。Y可再生资源的消耗、加工,以及小环境污染的独特优势,是环保型低碳产业,未来天然高分子材料等可再生资源将得到广泛应用,特别是木材中的木材,真正的木材材料将越来越多。未来很受欢迎;合成高分子材料作为不可再生资源,将被耗尽,而且通常会污染环境和消耗资源,但这种材料具有重要的功能和作用,未来的发展将具有这种功能和作用的材料取代现有的合成高分子材料;在有机非金属材料是不可再生资源,但相对合成高分子材料而言,此类材料或资源丰富,且污染较小,未来将在一定时期内得到广泛应用;金属材料是不可再生资源,但可以回收利用,有很好的使用前景,未来将越来越多的PA。应注重金属零件的开发,能开发出更简化的工艺,更经济、更强大、材料更为金属零件;目前整体复合材料应用状况良好,但对石油化工产品的依赖性很强,同时,鉴于传统材料的不足。S,New,符合低碳材料的特点,新型复合材料的开发利用将是一个很大的领域(Behera和Sarkar,2016)。

Commonly used materials, natural polymer materials is the only renewable resource, and the wood material is the only a carbon sink capacity, and woodiness material is accord with the characteristics of low carbon materials, especially wood, wood has all the characteristics of the low carbon material, timber industry has the advantages of low energy consumption of renewable resources, processing, and the unique advantage of small environmental pollution, is environmentally friendly low carbon industry, the future of natural polymer materials such as renewable resources of traditional materials will be widely used, especially the wood in the wood, real wood material will become more and more popular in the future; Synthetic polymer materials as the non-renewable resources, will be depleted, and usually will pollute the environment and consume resources, but this kind of material has an important function and role, and the future development have such function and role of material to replace the current synthetic polymer materials; Inorganic nonmetallic materials are non-renewable resources, but relatively synthetic polymer materials, such materials or resources is abundant, and less polluting, the future will be widely used in certain period of time; Metal material is non-renewable resources, but can be recycled, there is good use prospect, the future will be more and more paying attention to the development of the metal parts, can develop more simplified process is more economical, more powerful, materials of metal parts; At present the overall composite materials applied in good condition, but has very strong dependence for petrochemical products, at the same time, in view of the shortcomings of traditional materials, new, accord with the characteristics of low carbon materials development and utilization of new composite materials will be a lot(Behera&Sarkar, 2016).
 
2.0 Literature review
2.1 Zero and low-carbon buildings
In the construction sector, green and low-carbon building materials are materials that are not contaminated with the outside world, and are not radioactive hazards, and are called ecological building materials(Ramírez-Godínez,et.,al, 2015). At the same time, to complete its use functions and become a waste of time, can undertake reasonable and efficient recycling, classified according to different features, achieve the goal of recycling. For this kind of new environmental protection material, the preparation stage, the production stage and the sales channel should pass the more strict control. To ensure the cleanliness of each link, as the basis of the technical standard, make its indexes conform to the industry rules and norms and avoid deviations(Maet.,al, 2015). In the construction sector, the state vigorously promotes the use of energy-saving energy and the emission of pollutants such as waste gases. This led to the development of green, low-carbon building materials. People are increasingly looking at low-carbon life as a new fad. Consumption attitudes have changed. Research in the field of technology to meet this need, the numerous green low carbon building materials, such as organic glass, such as ecological cement, and put into production, can be widely applied in the field of architecture. Compared with traditional construction materials, green low carbon building materials reduces the building itself and the pollution of surroundings, assure indoor environmental non-toxic, and is conducive to the user's physical and mental health(Tikhomirovet.,al, 2016). Often, this material is superior in energy efficiency, energy consumption and safety. Can purify room air clearly, protect environment. It is widely used in house construction and home improvement. The new green and low carbon building materials show the improvement of the technical level of the construction area, which is the focus of the development of the construction materials(Ul'yanov, Zakharov, &Pospelova, 2015).
2.2 Natural polymer materials
The common feature of natural polymers is that the material is renewable, which guarantees the source of permanent raw materials; In the manufacturing process, because the material is soft, easy to process and consumes less energy; Because they're natural materials and they're less polluted; When used, the material does not produce new pollution; Abandoned after basic can all be recycled, be able to make other material or fuel can do, even if some materials cannot be recycled, but because it is a natural material will not have damage to the environment and in all such material belongs to a good low carbon materials(Ryaposov, Kleiner, &Shatsov, 2013).
2.3 Low carbon modified mother grain
Low carbon plastic is treated with modified non-metallic inorganic mineral powders, and plastic raw materials mixed use, thereby reducing plastic heat enthalpy, plastic raw materials to reduce costs, save energy consumption in machining process of, and don't reduce the physical properties of plastic manufactured goods(Shiet.,al, 2012). When plastic waste incineration is processed, carbon dioxide emissions can be greatly reduced.
2.4 Environmental degradation mother grain
Low carbon environmental degradation plastic refers to the same or similar, the physical indexes and general plastics in inventory and probation performance stability, abandoned, in the natural environment, the sun, the soil moisture, oxygen, microorganisms, in 3 ~ 6 months, the degradation of the natural environment in pairs harmless low molecular substances, the final degradation of new plastic for carbon dioxide and water (Baojianet.,al, 2016). There are three types of low-carbon biodegradable plastics that have been successfully marketed: biodegradable plastics. This product cheaper than ordinary plastic, made of it after the packaging waste, in the natural environment, generate 3-6 months, phenol, aldehyde, ketone, alcohol, ester, such as new materials, under the biological assimilation, into a good organic fertilizer plant growth, the resulting carbon dioxide and water and starch degradable plastics. The product is modified with a 60% ratio of starch to polyethylene(Yuxiang&Jianhong, 2015).
